WARNING: RISK OF BURSTING

Air Tank: On February 26, 2002, the U.S. Consumer Product Safety Commission published Release # 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent upon several factors, some of which include operating conditions, ambient conditions, proper installations, field modifications, and the level of maintenance. The exact effect of these factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the inner wall of the air receiver tank can cause the air tank to unexpectedly rupture allowing pressurized air to suddenly and forcefully escape, posing risk of injury to consumers.
Your compressor air tank must be removed from service by the end of the year shown on your tank warning label. The following conditions could lead to a weakening of the air tank, and result in a violent air tank explosion:

WARNING: Some dust contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm such as asbestos and lead in lead-based paint.

Failure to properly drain condensed water from the air tank, causing rust and thinning of the steel air tank.| Drain the air tank daily or after each use. If the air tank develops a leak, replace it immediately with a new air tank or replace the entire compressor.
Modifications or attempted repairs to the air tank.| Never drill into, weld, or make any modifications to the air tank or its attachments. Never attempt to repair a damaged or leaking air tank. Replace with a new air tank.
Unauthorized modifications to the safety valve or any other components which control air tank pressure.| The air tank is designed to withstand specific operating pressures. Never make adjustments or parts substitutions to alter the factory set operating pressures.
Attachments & Accessories: Exceeding the pressure rating of air tools, spray guns, air-operated accessories, tires, and other inflatables can cause them to explode or fly apart, and could result in serious injury.| Follow the equipment manufacturer’s recommendation and never exceed the maximum allowable pressure rating of attachments. Never use a compressor to inflate small low- pressure objects such as children’s toys, footballs, basketballs, etc.
Tires: Overinflation of tires could result in serious injury and property damage.| Use a tire pressure gauge to check the tire’s pressure before each use and while inflating tires; see the tire sidewall for the correct tire pressure.
| NOTE: Air tanks, compressors, and similar equipment used to inflate tires can fill small tires very rapidly. Adjust the pressure regulator on the air supply to no more than the rating of the tire pressure. Add air in small increments and frequently use the tire gauge to prevent overinflation.

WARNING: RISK OF ELECTRICAL SHOCK

Your air compressor is powered by electricity. Like any other electrically powered device, if it is not used properly it may cause electric shock.| Never operate the compressor outdoors when it is raining or in wet conditions. Never operate the compressor with protective covers removed or damaged.
Repairs attempted by unqualified personnel can result in serious injury or death by electrocution.| Authorized service center personnel should perform any repairs on this product.
Electrical Grounding: Failure to provide adequate grounding to this product could result in serious injury or death from electrocution.| Make certain that the electrical circuit to which the compressor is connected provides proper electrical grounding, correct voltage, and adequate fuse protection. See Grounding Instructions under Installation.

WARNING: RISK FROM FLYING OBJECTS

The compressed air stream can cause soft tissue damage to exposed skin and can propel dirt, chips, loose particles, and small objects at high speed, resulting in property damage or personal injury.| Always wear certified safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields when using the compressor. Never point any nozzle or sprayer toward any part of the body or at other people or animals. Always turn the compressor off and bleed pressure from the air hose and air tank before attempting maintenance, or attaching tools, or accessories.

Glossary

Become familiar with these terms before operating the unit.

• CFM: Cubic feet per minute.
• SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
• PSIG: Pounds per square inch gauge; a unit of measure of pressure.
• Code Certification: Products that bear one or more of the following marks: UL®, CUL, CULUS, ETL®, CETL, CETLUS, have been evaluated by OSHA-certified independent safety laboratories and meet the applicable Standards for Safety.
• Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your accessory. When the tank pressure drops to a certain lower level the motor will restart automatically. The low pressure at which the motor automatically restarts is called “cut-in” pressure.
• Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called “cut-out” pressure.
• Branch Circuit: Circuit carrying electricity from electrical panel to outlet.
• Duty Cycle: For proper operation of your air compressor, it is recommended that a 50% duty cycle be maintained; that is, the air compressor should not run more than 5 minutes in any 10 minutes.

Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference.

Description of Operation (Fig. A)
Become familiar with these controls before operating the unit.

• On(I)/Off(O) Switch: Place this switch 4 in the On(I) position to provide automatic power to the pressure switch and Off(O) to remove power at the end of each use.

• Pressure Switch (not shown) : The pressure switch automatically starts the motor when the air tank pressure drops below the factory set “cut-in” pressure. It stops the motor when the air tank pressure reaches the factory-set “cut-out” pressure.

• Safety Valve: If the pressure switch does not shut off the air compressor at its “cut-out” pressure setting, the safety valve 8 will protect against high pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch “cut-out” setting).

• Tank Pressure Gauge: The tank pressure gauge 5
  indicates the reserve air pressure in the tank.

• Outlet Pressure Gauge: The outlet pressure gauge 9 indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure.

• Regulator: Controls the air pressure shown on the outlet pressure gauge. Turn regulator knob 7 clockwise to increase pressure and counterclockwise to decrease pressure.

• Cooling System (not shown): This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled.

• Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above what is required at the air outlet.

• Drain Valve: The drain valve 10 is located at the base of the air tank and is used to drain condensation at the end of each use.

• Check Valve (not shown): When the air compressor is operating, the check valve is “open”, allowing compressed air to enter the air tank. When the air compressor reaches “cut-out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank.

• Motor Overload Protector (not shown): The motor has a thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting.

• To restart:

  • Set the On/Off switch to “Off” and unplug the unit.
  • Allow the motor to cool.
  • Plug the power cord into the correct branch circuit receptacle.

• Set the On/Off switch to the “On” position. Quick Connects: The Quick Connects 6 accepts industrial quick connect plugs. The two quick-connect bodies allow the use of two tools at the same time.
